Method and system for restricting the usage of payment accounts

ABSTRACT

A user&#39;s ability to spend and/or receive funds for payment accounts maintained in an electronic wallet are limited. These limitations include restrictions on where the user is able to spend the funds in a payment account (e.g., at which merchants the funds can be spent, whether the funds can be withdrawn from an ATM, etc.). These limitations may also include restrictions on what other payment accounts the user can receive funds from and/or transfer funds to, thereby limiting person-to-person fund transfers.

TECHNICAL FIELD

This invention relates to electronic commerce, and more particularly torestricting the usage of payment accounts.

BACKGROUND OF THE INVENTION

As computer systems throughout the world are becoming increasinglyconnected via the Internet, the uses for the Internet are similarlyexpanding. One rapidly growing use of the Internet is for electroniccommerce, where merchants make goods and/or services available forpurchase “on-line” via the Internet. Such purchases may be delivered viathe Internet (e.g., software downloaded from the merchant to thepurchaser's computer) or alternatively delivered via more traditionalin-person routes (e.g., mailing a product using the postal service).

Although the types and sources of goods and/or services available forpurchase on-line have increased, difficulties have been encountered inproviding a way for users to pay for these purchases. One solution is toprovide an electronic wallet for each user where he or she can storeaccount and address information for multiple different types ofaccounts, such as credit cards, debit cards, gift certificates, rebates,etc. One such solution is described in co-pending application Ser. No.09/675,466, entitled “Integrating Payment accounts And An ElectronicWallet”, to Arnold Blinn, Joseph Coco, and Greg Marks.

However, problems can be encountered when using electronic walletsbecause there is typically little or no ability to restrict the usage ofaccounts identified in the wallet. While a credit card stored in awallet could be spent at any location that accepts this credit card, itmay be desirable for other types of accounts to be restricted in howthey can be spent. It would be desirable, for example, for a giftcertificate account to be redeemable only at a restricted set ofmerchants. If the gift certificate account is a new payment accountmechanism this restriction can be built into the protocol for redemptionof the gift certificate. However, a gift certificate account may bebased on a credit card network (e.g. Visa® and credit card accountnumbering format (e.g., based on a Visa® card format). Although thegiver of the gift certificate may wish that the recipient use the giftcertificate at only certain merchants, if the gift certificate is basedon the Visa® account number format there is typically nothing preventingthe recipient from using the gift certificate anywhere that a Visa® cardis accepted.

The invention described below addresses these disadvantages, providingrestricted usage of payment accounts.

SUMMARY OF THE INVENTION

A method and system for restricting the usage of payment accounts isdescribed herein.

According to one aspect, payment accounts maintained in an electronicwallet are restricted to being spent at only a particular set of one ormore merchants. The set of merchants can be a static set, oralternatively a dynamic set with the merchants that belong to the setchanging over time. When the user attempts to purchase goods and/orservices at a merchant using a particular payment account, a check ismade to verify that the restrictions on the payment account permit theuser to make purchases at that merchant.

According to another aspect, restrictions limit the ability of funds tobe transferred into payment accounts or transferred to other paymentaccounts. The payment account is limited so that funds can be added to(or withdrawn from) the payment account only from (or to) certainindividuals. Such limitations prevent the user from transferring fundsto particular other individuals, or receiving funds from particularother individuals (e.g., a parent may establish a child's paymentaccount so that only the parent can add funds to it, not otherindividuals the child may encounter on the Internet).

According to another aspect, different payment accounts can be combined,thereby increasing the funds in one of the accounts (or creating a newpayment account). When combining accounts, the restrictions on the newlycreated account (or account with increased funds) are a subset of therestrictions of the original accounts that were combined. In otherwords, the newly created account (or account with increased funds) canonly be used in the same manner as both of the source accounts couldhave been used.

According to another aspect, merchant-specific payment accounts can beestablished and corresponding physical cards (e.g., credit cards orsmart cards) issued to users. An account number is stored on the cardalong with restrictions that limit the card to being used only at thespecific merchant. The new payment account information is alsocommunicated to an account processing network so that subsequent use ofthe card can be verified. This system allows merchants to issue paymentaccounts (e.g., gift certificates or rebates) taking advantage of anaccount processing network managed by someone other than the merchant.

DETAILED DESCRIPTION

FIG. 1 is a block diagram illustrating an exemplary network environmentsuch as may be used in accordance with certain embodiments of theinvention. In the network environment 100 of FIG. 1, multiple clients102, multiple merchant servers 104, and a wallet server 106 areillustrated coupled together via a network 108. Network 108 representsany of a wide variety of wired and/or wireless networks, includingpublic and/or private networks (such as the Internet, local areanetworks (LANs), wide area networks (WANs), etc.). Clients 102 andservers 104, 106 can be coupled to network 108 in any of a wide varietyof conventional manners, such as wired or wireless modems, directnetwork connections, etc.

Clients 102 communicate with servers 104, 106 using one or moreconventional protocols. In one implementation, network 108 is theInternet which supports the World Wide Web. The World Wide Web (alsoreferred to as simply the “Web”) is a collection of documents (referredto as “Web pages”) that users can view or otherwise render and whichtypically include links to one or more other pages that the user canaccess. Information is communicated among clients 102 and servers 104using, for example, the Hypertext Transfer Protocol (HTTP), althoughother protocols (either public or proprietary) could alternatively beused. Web pages are created in a markup language, such as the HypertextMarkup Language (HTML) or the eXtensible Markup Language (XML), althoughother languages could alternatively be used.

Wallet server 106 maintains an electronic “wallet” for each of multipleusers of clients 102. Inside his or her electronic wallet, a user isable to store information regarding various accounts, some of which aretraditional credit card accounts and others of which are referred to as“payment accounts”. As used herein, a “payment account” refers to anaccount that has a monetary value associated with it (which may bechanged), rather than a line of credit as is associated with traditionalcredit card accounts. The user is able, via a Web browser 110 running ona client 102, to use the payment accounts to make purchases on-line andalso to manipulate the payment accounts. Such manipulation includes, forexample, setting up new payment accounts, changing information inpreviously created payment accounts, adding funds to payment accounts,transferring value between payment accounts, etc.

During operation, Web browser 110 accesses a Web page hosted by amerchant server 104. A user is able, via Web browser 110, to purchasegoods and/or services from the merchant via the Web page hosted by themerchant server 104. During the purchasing process, Web browser 110receives, from wallet server 106, an indication of the accounts(including payment accounts and traditional credit card accounts)available to the user. Web browser 110 allows the user to select one ofthese available accounts to purchase the goods and/or services, andforwards payment information for the selected account to the merchantserver 104.

Various restrictions can be imposed on the payment accounts duringoperation on a per-account basis. Such restrictions limit the ability ofthe user to spend funds from his or her account(s) and/or the ability ofthe user to receive additional funds into his or her pre-existingaccount(s). By so restricting the payment accounts, the accounts can bemaintained in a centralized location for easy identification and accessby the user, while at the same time allowing the user's ability to spendand/or receive funds from or to the different accounts to be limited.

FIG. 2 illustrates an example of a suitable operating environment inwhich at least portions of the invention may be implemented. Theillustrated operating environment is only one example of a suitableoperating environment and is not intended to suggest any limitation asto the scope of use or functionality of the invention. Other well knowncomputing systems, environments, and/or configurations that may besuitable for use with the invention include, but are not limited to,personal computers, server computers, hand-held or laptop devices,multiprocessor systems, microprocessor-based systems, programmableconsumer electronics, gaming consoles, cellular telephones, publicterminals or kiosks, wearable computers, network PCs, minicomputers,mainframe computers, distributed computing environments that include anyof the above systems or devices, and the like.

Alternatively, the invention may be implemented in hardware or acombination of hardware, software, and/or firmware. For example, one ormore application specific integrated circuits (ASICs) could be designedor programmed to carry out the invention.

FIG. 2 shows a general example of a computer 142 that can be used inaccordance with the invention. Computer 142 is shown as an example of acomputer that can perform the functions of a client 102 or server 104 or106 of FIG. 1. Computer 142 includes one or more processors orprocessing units 144, a system memory 146, and a bus 148 that couplesvarious system components including the system memory 146 to processors144.

The bus 148 represents one or more of any of several types of busstructures, including a memory bus or memory controller, a peripheralbus, an accelerated graphics port, and a processor or local bus usingany of a variety of bus architectures. The system memory 146 includesread only memory (ROM) 150 and random access memory (RAM) 152. A basicinput/output system (BIOS) 154, containing the basic routines that helpto transfer information between elements within computer 142, such asduring start-up, is stored in ROM 150. Computer 142 further includes ahard disk drive 156 for reading from and writing to a hard disk, notshown, connected to bus 148 via a hard disk drive interface 157 (e.g., aSCSI, ATA, or other type of interface); a magnetic disk drive 158 forreading from and writing to a removable magnetic disk 160, connected tobus 148 via a magnetic disk drive interface 161; and an optical diskdrive 162 for reading from and/or writing to a removable optical disk164 such as a CD ROM, DVD, or other optical media, connected to bus 148via an optical drive interface 165. The drives and their associatedcomputer-readable media provide nonvolatile storage of computer readableinstructions, data structures, program modules and other data forcomputer 142. Although the exemplary environment described hereinemploys a hard disk, a removable magnetic disk 160 and a removableoptical disk 164, it will be appreciated by those skilled in the artthat other types of computer readable media which can store data that isaccessible by a computer, such as magnetic cassettes, flash memorycards, random access memories (RAMs), read only memories (ROM), and thelike, may also be used in the exemplary operating environment.

A number of program modules may be stored on the hard disk, magneticdisk 160, optical disk 164, ROM 150, or RAM 152, including an operatingsystem 170, one or more application programs 172, other program modules174, and program data 176. A user may enter commands and informationinto computer 142 through input devices such as keyboard 178 andpointing device 180. Other input devices (not shown) may include amicrophone, joystick, game pad, satellite dish, scanner, or the like.These and other input devices are connected to the processing unit 144through an interface 168 that is coupled to the system bus (e.g., aserial port interface, a parallel port interface, a universal serial bus(USB) interface, etc.). A monitor 184 or other type of display device isalso connected to the system bus 148 via an interface, such as a videoadapter 186. In addition to the monitor, personal computers typicallyinclude other peripheral output devices (not shown) such as speakers andprinters.

Computer 142 operates in a networked environment using logicalconnections to one or more remote computers, such as a remote computer188. The remote computer 188 may be another personal computer, a server,a router, a network PC, a peer device or other common network node, andtypically includes many or all of the elements described above relativeto computer 142, although only a memory storage device 190 has beenillustrated in FIG. 2. The logical connections depicted in FIG. 2include a local area network (LAN) 192 and a wide area network (WAN)194. Such networking environments are commonplace in offices,enterprise-wide computer networks, intranets, and the Internet. Incertain embodiments of the invention, computer 142 executes an InternetWeb browser program (which may optionally be integrated into theoperating system 170) such as the “Internet Explorer” Web browsermanufactured and distributed by Microsoft Corporation of Redmond, Wash.

When used in a LAN networking environment, computer 142 is connected tothe local network 192 through a network interface or adapter 196. Whenused in a WAN networking environment, computer 142 typically includes amodem 198 or other means for establishing communications over the widearea network 194, such as the Internet. The modem 198, which may beinternal or external, is connected to the system bus 148 via a serialport interface 168. In a networked environment, program modules depictedrelative to the personal computer 142, or portions thereof, may bestored in the remote memory storage device. It will be appreciated thatthe network connections shown are exemplary and other means ofestablishing a communications link between the computers may be used.

Computer 142 also includes a broadcast tuner 200. Broadcast tuner 200receives broadcast signals either directly (e.g., analog or digitalcable transmissions fed directly into tuner 200) or via a receptiondevice (e.g., via antenna 110 or satellite dish 114 of FIG. 1).

Computer 142 typically includes at least some form of computer readablemedia. Computer readable media can be any available media that can beaccessed by computer 142. By way of example, and not limitation,computer readable media may comprise computer storage media andcommunication media. Computer storage media includes volatile andnonvolatile, removable and non-removable media implemented in any methodor technology for storage of information such as computer readableinstructions, data structures, program modules or other data. Computerstorage media includes, but is not limited to, RAM, ROM, EEPROM, flashmemory or other memory technology, CD-ROM, digital versatile disks (DVD)or other optical storage, magnetic cassettes, magnetic tape, magneticdisk storage or other magnetic storage devices, or any other media whichcan be used to store the desired information and which can be accessedby computer 142. Communication media typically embodies computerreadable instructions, data structures, program modules or other data ina modulated data signal such as a carrier wave or other transportmechanism and includes any information delivery media. The term“modulated data signal” means a signal that has one or more of itscharacteristics set or changed in such a manner as to encode informationin the signal. By way of example, and not limitation, communicationmedia includes wired media such as wired network or direct-wiredconnection, and wireless media such as acoustic, RF, infrared and otherwireless media. Combinations of any of the above should also be includedwithin the scope of computer readable media.

The invention has been described in part in the general context ofcomputer-executable instructions, such as program modules, executed byone or more computers or other devices. Generally, program modulesinclude routines, programs, objects, components, data structures, etc.that perform particular tasks or implement particular abstract datatypes. Typically the functionality of the program modules may becombined or distributed as desired in various embodiments.

For purposes of illustration, programs and other executable programcomponents such as the operating system are illustrated herein asdiscrete blocks, although it is recognized that such programs andcomponents reside at various times in different storage components ofthe computer, and are executed by the data processor(s) of the computer.

FIG. 3 illustrates an exemplary suite of services including anelectronic wallet such as may be used in certain embodiments of theinvention. The suite of services 220 includes an electronic wallet 222,an authentication module 224, and optionally an account monitor 227. Thesuite of services 220 may be made available to users from the sameremote server (such as server 106 of FIG. 1) or alternatively differentservers (for example, electronic wallet 222 may be made available fromthe first server while authentication module 224 is made available fromanother server).

In the illustrated example, a user first signs in or logs in to services220 using his or her Web browser. This sign-in may be accomplisheddirectly by the user accessing a Web page hosted by the server thatprovides services 220, or alternatively indirectly by the user accessinganother Web page that redirects the user's Web browser to services 220.Sign-in is managed by authentication module 224, which verifies theidentity of the user signing in. This verification can be performed inany of a wide variety of conventional manners, such as using a user IDand associated password, as well as any of numerous cryptographic andother techniques for authenticating the user. Once the user's identityis verified, the user is able to access the information maintained byservices 220.

Electronic wallet 222 stores various purchasing and address informationfor a user. This stored information includes user identificationinformation 228, address information 230, and information for multipleaccounts (including both payment accounts and traditional credit cardaccounts) 232. User identification information 228 includes variousinformation uniquely identifying the user electronic wallet 222 belongsto as well as information about the user's electronic wallet. Table Iidentifies the user identification information maintained in oneexemplary implementation.

TABLE I Name Description MemberId The user ID. ProfileVersion Anincremental counter starting at 1 and incremented each time theelectronic wallet is updated/modified. CurrentAddress The AddressID ofone of the user's addresses. Often used as the default shipping addressfor purchased goods and/or services. CurrentCard The ID of one of theuser's accounts, which can be a payment account or traditional creditcard account.

Address information 230 includes various addresses corresponding to theuser. These addresses can include, for example, a home address, abusiness address, shipping addresses for the user or others (e.g.,friends or family), a credit card billing address, etc. Table IIidentifies the information maintained for each address in one exemplaryimplementation.

TABLE II Name Description AddressID Unique (for the user) identifier ofthe address. MemberId The user ID. Fname First name of person foraddress. Lname Last name of person for address. Addr1 First line ofaddress (e.g., to include company or street name). Addr2 Second line ofaddress (e.g., to include street name or apartment number). City Cityfor address. State State for address. PostalCode Postal code foraddress. Country Country for address. Phone Phone number correspondingto address. Email Email corresponding to address (could be the user, theperson identified in Fname and Lname fields, or someone else).FriendlyName User-friendly identifier of the address (e.g., “Home”,“Mom's Address”, etc.).

Multiple accounts 232 are illustrated with the electronic wallet 222. Inthe illustrated example, two credit cards 236, 238, a gift certificate240, a rebate account 242, a debit card 244, a cash account 246, anallowance account 248, and a reward account 249 are shown. It is to beappreciated that these accounts illustrated are exemplary only, andalternatively more or fewer accounts could be included in electronicwallet 222. Additionally, other types of accounts (not shown), such asMicro Payment accounts, may also be included in electronic wallet 222.Credit card accounts are accounts that correspond to the user's physicalcredit cards. Gift certificate payment accounts are accounts thatcorrespond to electronic gift certificates that have been given (orotherwise transferred) to the user. Rebate payment accounts are accountsthat correspond to electronic rebates that have been given (or otherwisetransferred) to the user, such as in response to the user's purchase ofa particular product. Reward payment accounts are accounts thatcorrespond to rewards that have been given to the user in exchange forcertain behavior (e.g., accessing certain web sites, making donations,being a long-term customer, registering a product within a certainperiod of time, etc.). Debit card payment accounts are accounts thatcorrespond to the user's physical debit cards (e.g., as issued by abank). Cash payment accounts are accounts that are analogous to physicalcash carried by the user. Cash payment accounts are similar to debitcard payment accounts in that they have a limited amount of fundsassociated with them and do not involve issuance of credit to the user.Allowance payment accounts are a special type of cash or debit cardpayment account that are designed to be given to children (with theadvantage of restricting the usage of the account)

Different types of accounts (e.g., credit cards, debit cards, giftcertificates, rebates, rewards, cash, allowance, etc.) can be includedin electronic wallet 222, as well as multiple accounts of the same type.Each of the different types of accounts is presented differently to theuser, allowing him or her to easily distinguish between accounts. Insome instances, logos corresponding to the account type (e.g., Visa® orthe issuer (e.g., the bank name) may be displayed to the user. However,even though the different account types are presented to the userdifferently, the different account types may share an underlying format.For example, gift certificates may use the same account numbering schemeas is used for Visa® cards.

Each of the accounts 232 includes payment information for the account.This payment information includes information that is passed to amerchant server to allow the user to purchase goods and/or services froma merchant. Table III identifies the information maintained for eachaccount 232 in one exemplary implementation. Note, however, that not allaccounts need include all of this information, and other accounts mayinclude additional information.

TABLE III Name Description ID Unique (for the user) identifier of theaccount. MemberId The user ID. Type An identifier of the type ofaccount. Num An account number for the account. For credit cards, thecredit card number. Num2 A secondary number for identifying the card.For Visa cards this could be the CVV2 (Card Verification Value 2). ExpAn expiration date of the account. BillingAddress The AddressID of oneof the address in the Addresses table. Name The name on the account.FriendlyName A user-friendly identifier of the account (e.g., “Joe'sVisa”, “Gift Certificate From Mom”, “Rebate from Microsoft ®”).Restrictions Restrictions associated with the payment account (e.g.,where funds corresponding to the payment account can be spent or wherenew funds to be added to the payment account can be received from).

Services 220 can be accessed by client Web browsers 250 for a variety ofdifferent purposes. A user may access services 220 directly, such as tomodify information in electronic wallet 222 (e.g., add a new paymentaccount, change an address, etc.). Modifications to electronic wallet222 may also be made by others, as discussed in more detail below. Awallet manager 234 transmits web pages to browser 250 with optionsallowing a user to add, delete, and modify accounts 232 and addresses230. A user may also access services 220 indirectly, such as when makinga purchase of goods or services from a merchant Web page 252. During thepurchasing process, Web browser 250 acts as an intermediary between themerchant Web page 252 and electronic wallet 222, as discussed in moredetail below.

When included in services 222, account monitor 227 monitors the usage ofpayment accounts within accounts 232 and prevents transactions if therestrictions on a payment account are violated. In one implementation,transactions involving the transfer of funds to and/or from paymentaccounts are passed through account monitor 227 prior to being returnedto the requesting web browser 250. Account monitor 227 compares theidentity of the recipient of funds from a payment account (oralternatively the source of funds for a payment account) to therestrictions associated with the payment account. If the restrictionsindicate that the recipient (or source) is acceptable, then accountmonitor 227 allows the transfer to continue. However, if therestrictions indicate that the recipient (or source) is unacceptable,then account monitor 227 prohibits the transfer. Account monitor 227 canprohibit the transfer in any of a variety of manners, such as simplyreturning an indication to web browser 250 that the transaction cannotbe completed.

Different types of restrictions can be imposed by the account monitor onpayment accounts on a per-payment account basis, limiting the user'sability to spend the funds from payment accounts (or receive additionalfunds into payment accounts). Restrictions on payment accounts can beclassified into two general types: merchant usage restrictions andpayment account transfer restrictions. Merchant usage restrictions referto restrictions on where the user is able to spend the funds in thepayment account. Payment account transfer restrictions refer torestrictions, for a particular payment account, on what other paymentaccounts the user can receive funds from and/or transfer funds to.

Merchant usage restrictions limit where (e.g., based on the identity ofthe merchant(s)) the user is able to spend funds associated with thepayment account. The payment account can be restricted to being spent atonly a set of one or more merchants. Which merchants the payment accountcan be spent at is identified when the payment account is established.For example, if a mother is giving her son a gift certificate paymentaccount, then the mother can identify, during the process of purchasingthe gift certificate, which on-line merchant(s) the gift certificatefunds can be spent at. The set of one or more merchants can be a staticset or a dynamic set that changes over time. By way of example, thepayment account may identify a static set of merchants (e.g., by name,numeric identifier, by Internet address, etc.) that funds associatedwith the account can be spent at. Alternatively, the payment account mayidentify a particular group of merchants (e.g., those corresponding to aparticular on-line community, such as an on-line shopping mall). Anexample of such a group of merchants are the MSN® Shopping merchantsaccessible via the MSN® Web site. The actual merchants within the groupmay change over time, and the restriction imposed on the payment accountis checked when funds for the payment account are to be spent—if themerchant where funds are to be spent is part of the group at the timethe funds are to be spent, then the purchase is allowed; otherwise, thepurchase is not allowed, even if the merchant were a part of the groupwhen the payment account was created.

Merchant usage restrictions can further limit the user's ability to usethe payment account off-line. For example, the restrictions may indicatewhether a physical card (e.g., analogous to a credit card or smart card)can be issued to the user. If such a physical card can be issued to theuser, then the user is able to spend the funds from the payment accountin a traditional off-line manner using the physical card. Therestrictions may also indicate whether the user can obtain “cash” fromthe account, including cash in-hand, transfer to a checking or savingsaccount, etc. (e.g., if a physical card is issued to the user, whetherthe physical card can be used at an automated teller machine (ATM) forthe user to directly withdraw funds from the payment account).

Payment account transfer restrictions limit the ability of the user totransfer funds from (or receive funds in to) one of his or her paymentaccounts to (or from) the payment account of another. A payment accountmay be restricted to transferring funds to only one or more other users(e.g., identified by some unique identifier such as an email address). Apayment account may similarly be restricted to receiving funds from onlyone or more other users. For example, an allowance payment account usedby a child may be limited to receiving funds only from the child'sparents.

The restrictions on payment accounts also limit the user's ability tocombine funds from multiple ones of his or her payment accounts. By wayof example, assume that a user has two $50 gift certificates: one isrestricted to being spent only at Merchants A, B, and C, while the otheris restricted to being spent only at Merchants C, D, and E. If the userdesires to make a $100 purchase at Merchant C, then the user can combineboth gift certificates for the purchase (because both certificates areuseable at Merchant C). This would also entail either creating a newgift certificate account that is redeemable only at Merchant C, oralternatively modifying the restrictions on the account the two arecombined into to being redeemable only at Merchant C. However, if theuser desires to make a $100 purchase at any one of Merchants A, B, D, orE, then the user is limited to using only one of the $50 giftcertificates (having to come up with the remaining $50 from some othersource).

Each payment account may also have an expiration date associated withit. Once the expiration date has passed, the payment account is nolonger valid and cannot be used for purchases (the expiration date iscompared to the current date at the time the funds are trying to bespent, and authorization to spend the funds fails if the expiration datehas passed). If two payment accounts are combined, then the resultantcombination is also limited by the earliest expiration date of the twoaccounts (if any). Following the previous example, assume that one ofthe $50 gift certificates has an expiration date of Jan. 1, 1999 and theother has an expiration date of Jun. 1, 1999. The newly created $100gift certificate (whether a new account or one of the original accountswith new funds added to it) would then have an expiration date of Jan.1, 1999.

The combination of funds into a payment account occurs prior topurchase, and may be just before the purchase (e.g., when the userchecks out at an on-line merchant) or alternatively a substantial periodof time prior to the purchase (e.g., weeks or months). If funds frommultiple source payment accounts are to be combined, then either a newpayment account is created or the funds available on one of the sourcepayment accounts is increased (and the funds on the other source paymentaccount decreased). Regardless of whether a new payment account iscreated or a pre-existing payment account is modified, the paymentaccount that the funds are transferred to has restrictions that satisfythe restrictions of both source payment accounts. By way of example,assume that a user has two $50 gift certificates that he desires tocombine into a single gift certificate: the first gift certificate isrestricted to being spent only at Merchants A, B, and C, while thesecond gift certificate is restricted to being spent only at MerchantsC, D, and E. If funds from the second gift certificate (either all or aportion of the funds) are to be transferred to the first giftcertificate, then the restrictions on the first gift certificate arechanged so that the first gift certificate is restricted to being spentonly at Merchant C (or a new gift certificate is created that isrestricted to being spent only at Merchant C).

The combination of payment accounts and creation of new restrictions maybe a reversible or irreversible process. For instance, once funds fromthe second gift certificate in the previous example are added to thefirst gift certificate, the restriction changes on the first giftcertificate may be irreversible (the funds from the first giftcertificate will always be limited to being spent at Merchant C—nopurchases form Merchants A or B can be made with the funds).Alternatively, the device performing the combining (e.g., wallet manager234) may maintain a record of what combinations were made and allow themto be later reversed or “un-done” by the user. Additional limitationsmay be made on such reversals, such as allowing the reversal only if nofunds from the combined account have been spent since the combination.

In addition to combining payment accounts, a single payment account mayalso be separated or “split” into multiple payment accounts. Forexample, a $100 gift certificate may be separated into one $50 giftcertificate and two $25 gift certificates. Each of the newly createdpayment accounts is restricted to being spent at the same merchants asthe original payment account, and the expiration date of each of thenewly created payment accounts is the same as the original paymentaccount. Analogous to the combining of payment accounts, the splittingof payment accounts may be a reversible or irreversible process.

Electronic wallet 222 further provides a centralized location at which auser can store all of the information necessary to make purchaseson-line. The user can have multiple different types of payment accountsin his or her wallet and have them readily accessible regardless oftheir source. For example, the user need not remember what giftcertificates and/or rebates he or she has received, but simply accesshis or her electronic wallet to identify the available gift certificatesand rebates. Additionally, using the centralized storage of accounts 232and addresses 230, a user is able to simply select from already-entereddata to make purchases at a wide variety of on-line merchants, therebyreducing the amount of data entry required by the user and reducing thechances of errors in entering the information at numerous locations.

FIG. 4 is a block diagram illustrating an exemplary environment in whichpurchases of goods and/or services can be made using an electronicwallet. The user of a client 102, via a Web browser 110 running onclient 102, can access both a merchant server 104 and wallet server 106.Wallet server 106 includes multiple electronic wallets 272, 274, and276, each corresponding to a different user. The user can manipulatefunds in his or her wallet, and has no access to wallets of other usersstored on wallet server 106.

A user can receive funds into, or spend funds from, any of the accountsidentified in his or her electronic wallet (subject to any restrictionson the payment accounts). The receipt or expenditure of funds can beperformed directly from wallet server 106 (e.g., a user transferringfunds from one of his or her payment account accounts to the account ofanother user), or indirectly from wallet server 106 (e.g., via amerchant server 104). It should be noted, however, that the paymentaccounts within an electronic wallet only identify accounts and moneythat the user has access to—the payment accounts do not actually storemoney themselves. For example, a debit card payment account may store adebit card number and corresponding expiration date. However, the actualmoney for the account (the funds that the user has access to using thatdebit card) is maintained by the bank (or other issuer) of the debitcard.

When funds are being transferred from a payment account to a merchant(e.g., being spent), the identification information stored in theelectronic wallet for the payment account (e.g., account number, fraudprotection number (if any), expiration date (if any), and billingaddress (if any)) is transferred first to the merchant and then from themerchant to the issuing bank (or agent thereof) 278. This first transfer(to the merchant) can be simply done through an HTTP POST from thewallet server to the merchant server. This second transfer (to theissuing bank) is typically performed by communicating the information toa universal credit card platform or network 280, such as that providedby First Data Corp. (FDC) of Atlanta, Ga. The universal credit cardplatform 280 verifies the integrity of the account number and the fundsavailable, and reports the information to the requester (e.g., merchantserver 104). Account number integrity can be verified in any of a widevariety of conventional manners. Alternatively, rather thancommunicating directly with the platform 280, the requester maycommunicate with platform 280 via an intermediary 282. Intermediary 282may, for example, receive information for multiple purchases and combinethem for submission to platform 280 as a group.

Note that certain account types (e.g., gift certificates paymentaccounts) might not be backed by a traditional bank or credit card. Asimple account and account balance might be maintained in suchsituations (e.g., at wallet server 106 or another device), although theprinciples of spending it are the same as above.

Funds can be transferred into a payment account from other accounts inthe same electronic wallet (e.g., combining accounts), or alternativelyfrom external sources. To receive funds into a payment account, walletmanager 234 receives an indication of the payment account the funds areto be transferred into and verifies the availability of the funds (e.g.,via intermediary 282 or universal credit card platform 280), analogousto the merchant's verification of fund availability discussed above.Assuming the desired funds are available (and the addition of funds tothe payment account is not restricted), the wallet server adds the fundsto the indicated payment account by forwarding an indication of thedesired funds to the appropriate payment account issuer (e.g., viaintermediary 282 or universal credit card platform 280), or by updatingthe appropriate indication in the electronic wallet (e.g., if theelectronic wallet holds the funds). Similarly, the wallet server removesthe funds from the source account by forwarding an indication of theremoval (or other charge) to the appropriate source account issuer(e.g., via intermediary 282 or universal credit card platform 280).

Additionally, payment accounts can be added to an electronic wallet 222by the user that corresponds to the wallet 222 or alternatively anotheruser. For example, a user may desire to enter information for a newpayment account, such as a new debit card he or she recently received.The user signs-in to his or her electronic wallet 222 via authenticationmodule 224 and adds the information for the new payment account via aninterface (e.g., web pages) presented by wallet manager 234.

Additionally, users may add payment accounts to other users' electronicwallets either directly or indirectly. To directly add a payment accountto another user's electronic wallet (e.g., a new allowance account or anincrease in the amount of funds in an allowance account), the user signsin to his or her own electronic wallet, and then identifies, via walletmanager 234, the other user that the new payment account is to be addedto. Such additions may be automatic, or alternatively the other user maybe prompted (e.g., the next time he or she signs-in to his or heraccount) to approve the receipt. To indirectly add a payment account toanother user's account (e.g., a gift certificate or rebate), the useroperates through an intermediary (such as an electronic mail system).The intermediary forwards an indication (e.g., an email message) to theuser of the new payment account. The user can either copy informationfrom the email message himself or herself to create the new paymentaccount, or alternatively select a link embedded in the email message.Selection of the email message causes the source of the new paymentaccount (e.g., a gift certificate or rebate portal) to communicate withthe wallet manager 234, identifying the user that the new paymentaccount is to be added for.

An account monitor 284 can be implemented in any one or more of walletserver 106, intermediary 282, universal credit card platform 280, and ora bank 278. Account monitor 284 monitors the fund transfers for accountsmaintained in electronic wallets 272, 274, and 276, and verifies thatthe restrictions (if any) imposed on such accounts are not beingviolated. If the restrictions are not being violated, then the fundtransfer is permitted and allowed to proceed; however, if restrictionsare being violated, then the fund transfer is denied and not allowed toproceed. For example, if user B is attempting to spend funds from a giftcertificate payment account at Merchant A but the gift certificatepayment account is restricted to being spent only at Merchant D orMerchant E, then when the attempted purchase is made account monitor 284denies the purchase. When account monitor 284 is implemented inintermediary 282, platform 280, or bank 278, the denial of a fundtransfer can be indicated back to merchant server 104 (or wallet server106) with specific information as to why the transfer was denied (e.g.,an indication that restrictions were violated), or alternatively withoutsuch specific information (e.g., simply indicating that the accountcannot be verified for the desired fund transfer).

FIG. 5 is a block diagram illustrating an exemplary data flow whenmaking a purchase from a merchant Web page using an electronic wallet inaccordance with certain embodiments of the invention. A user browses or“surfs” the Internet via a browser 110 executing on a client 102. Theuser accesses one or more Web pages 252 at a merchant server(s) thatidentify goods and/or services that the user desires to purchase. Theuser selects these goods and/or services (act 300) in a conventionalmanner via browser 110. When the goods and/or services are selected,merchant server 104 displays a product purchase Web page 252 thatincludes a link to electronic wallet 222 (act 302). The product purchaseWeb page 252 typically displays the products and/or services to the userand gives him or her the option to purchase the displayed productsand/or services by selecting the link to electronic wallet 222. Oftentimes, these product purchase Web pages are referred to as “checkout” or“shopping cart” pages.

The user then selects (e.g., “clicks on”) the link to the electronicwallet 222, which causes browser 110 to access wallet server 106 (act304). Various information can be embedded in the link to the electronicwallet (e.g., included as parameters of a URL corresponding to walletserver 106). The amount of the user's desired purchase may also beembedded in the link. Table IV identifies the information embedded inthe link to the electronic wallet in one exemplary implementation.

TABLE IV Argument Description Partner ID An identifier of the merchantsite. Language Specifies the language to display the wallet pages in.Code ID Return URL URL that the wallet server should return to afteruser selections are made. Data Requested Identifies what data isrequested by merchant server: e.g., shipping address only, accountinformation only (including billing address, if any), or both shippingaddress and account information (with billing address). Allows onlyappropriate options to be presented to the user on the wallet page(e.g., account information is not displayed for user selection if themerchant only requests the shipping address). Cards List of accountsthat are acceptable to the merchant. Preferred Card Identifies apreferred type of account, allowing the wallet page to include a logo orother identifier of the preferred type of account (either a traditionalcredit card account or a payment account).

The response by wallet server 106 varies, depending on whether the userof client 102 is already logged in to his or her wallet. If the user hasnot logged in to his or her wallet yet, then wallet server 106 connectsbrowser 110 to a sign-in/authentication module (module 224 of FIG. 3).Authentication module 224 authenticates the user (act 306), associatingthe user of browser 110 with the correct electronic wallet 222. Thisallows the correct one of multiple electronic wallets stored at server106 (that is, the electronic wallet that includes the user'sinformation) to be associated with the user of browser 110. Once theuser is logged in, a wallet page that includes the contents (orreferences to the contents) of the user's electronic wallet 222 can bedisplayed to him or her (act 308). If, on the other hand, the user isalready logged in to his or her wallet, then the wallet page can bedisplayed to the user (act 308) without making the user repeat thesign-in process.

The wallet page displays to the user various information from his or herelectronic wallet 222. This information includes, for example, differentaccounts 232 from which the user can select to make his or herpurchases, different shipping addresses where the purchased goods are tobe delivered (or purchased services to be performed), different billingaddresses that correspond to different accounts 232, etc. Thesedifferent options can be displayed to the user in a wide variety ofdifferent manners, such as the use of drop-down or pull-down menus,selection boxes with multiple entries (and optionally scroll bars), aradio button corresponding to each selectable option, etc. In oneimplementation the billing address is tied to the account, so selectionof a new account automatically results in selection of the appropriatebilling address. The available options are controlled by the merchantcalling the wallet. For example, payment accounts not valid at themerchant might not be displayed, or alternatively displayed butdisabled. Additionally, the specification of shipping address may beoptional, as some merchants do not require this (they do not need it ordo not allow it to be different than a billing address on a creditcard).

Whatever options are selected by the user, their selection is forwardedto wallet server 106 (act 310). Based on these selections, wallet server106 accesses electronic wallet 222 to obtain the purchase informationfor the selected account and address information for the purchase (e.g.,shipping address and billing address for the account). This purchaseinformation can include, for example, all necessary information to usethe identified account (e.g., in the case of an account that is a creditcard, the necessary information may include a billing address and creditcard number). Some of this information (e.g., a credit card number) maynot have been initially transferred to browser 110 (e.g., an indicationof “My Visa” may have been sent in act 308, but not the actual creditcard number).

Wallet server 106 transfers this purchase information and addressinformation to browser 110 (act 312). This transfer is accomplished viaan HTML GET command, with at least some of the purchase and addressinformation (e.g., the account number and expiration date) in hiddenform fields. Upon receipt, browser 110 issues an HTTPS (HTTP over SSL)POST to the merchant web page (as indicated by the ReturnURL parameterin table IV), which forwards the purchase and address information tomerchant server 104 (act 314). Merchant server 104 then has thenecessary information to charge the purchase to the appropriate account,allowing the merchant to be paid and the user to receive the purchasedgoods and/or services. In one exemplary implementation, the purchase andaddress information is transferred from browser 110 to merchant server104 in accordance with the well-known Electronic Commerce ModelingLanguage (ECML).

Given the purchase and address information, merchant server 104 verifiesthat the desired purchase can be made. Merchant server 104 validates thefunds through a bank (e.g., bank 278 of FIG. 4) or a protocol specificto the account type being used to make the purchase. For example, for aVisa® account FDC could be used, while for other accounts the protocolmay be a proprietary protocol. By way of another example, for a giftcertificate payment account that conforms to the Visa® card format (oris convertible to the Visa® card format), the payment account would bevalidated through FDC, which communicates with a particular bank on theback end that validates the funds for the payment account and enforcesany restrictions on the payment account.

Various security measures can optionally be implemented within theprocess illustrated in FIG. 5 to maintain the security of confidentialuser information. Examples of such security measures includeestablishing secure links between client 102 and server 104 and/orserver 106 (e.g., using the HTTPS protocol), and encrypting informationbeing passed.

In the illustrated example, wallet server 106 does not store anindication of funds in the various payment accounts of a user'selectronic wallet. Rather, if such information is needed (e.g., todisplay to the user the funds still available to him or her from a giftcertificate) then wallet server 106 communicates with the issuer of theaccount (e.g., via universal credit card platform 280) to obtain acurrent balance available in the account. Alternatively, indications offunds available in one or more payment accounts may be stored in theuser's electronic wallet. For example, the value of a rebate paymentaccount may be stored in the electronic wallet, and updated when theuser spends a portion (or all) of the funds.

In situations where an identification of funds are stored in the user'selectronic wallet, then any transfers between accounts are accomplishedby updating the appropriate payment account balances in the electronicwallet. However, in situations where an external entity needs to be madeaware of the transfer (e.g., the account issuer), then the accountissuer is contacted to verify the availability of funds to betransferred (e.g., via intermediary 282 or platform 280 of FIG. 4). Ifsufficient funds are available, then the appropriate charge iscommunicated to the issuer of the source account and the appropriateaddition is communicated to the issuer of the destination account.

Wallet server 106 may also map one type of account to another type ofaccount. This mapping allows payment accounts to maintain their originalidentity in the eyes of the user while at the same time allowing them tobe viewed differently by a merchant. By way of example, a giftcertificate may be given to a user. The gift certificate includespurchasing information in the Visa® credit card format (or alternativelyin a format that can be converted to the Visa® credit card format). Whenthe user accesses his or her wallet, he or she sees the gift certificateas a gift certificate payment account—any association that the paymentaccount has with a Visa® card (or the Visa®(g card format) is hiddenfrom the user. However, when a purchase is made, wallet server 106communicates the purchase information for the gift certificate paymentaccount to the merchant server as if the purchase information were froma Visa®(g card. Any representation of the payment account to the user asa gift certificate is thus hidden from the merchant. This has theadvantage of allowing the merchant to accept the payment without doingany special work to accept a new payment account for purchase.

A user is able to maintain multiple different accounts in his or herelectronic wallet, and these accounts can be of the same or differenttypes. Not all merchants, however, may accept all of these differenttypes of accounts. By way of example, a user may store in his or herwallet two credit card accounts (one for a Visa®(g card and one for anAmerican Express®(g) card) as well as a gift certificate paymentaccount. Although illustrated to the user as a gift certificate, thegift certificate payment account may be of a format that can beconverted to a Visa® card format. A particular merchant (at which thegift certificate is redeemable), on the other hand, may only accept theVisa® credit card for purchases. In this example, the wallet serverwould thus include on the wallet page the Visa® card account and thegift certificate payment account. The American Express® card accountwould not be displayed because it is not useable by the user at thatmerchant (and cannot be converted to a useable format). Alternatively,the non-useable account(s) may be displayed to the user but displayed ina manner that indicates that it is not useable (for example, it may bepresented in a different font or different color, or in a separatesection identified as “not usable”).

In the discussion above, various actions are described as beingperformed at the wallet server. For example, conversions between accountformats are performed at the wallet server, purchase information for theaccounts selected by the user is retrieved in response to userselections, etc. Alternatively, some or all of these actions may becarried out at the client (e.g., an applet executing in browser 110 orother application executing on the client).

FIG. 6 is a flowchart illustrating an exemplary process for displayingaccounts useable for a purchase in accordance with certain embodimentsof the invention. The process of FIG. 6 is implemented by browser 110and wallet server 106, and may be implemented in software.

Initially, a request for a user purchase is received from a merchantserver (act 350). The accounts that are useable at that merchant arethen identified (act 352). These accounts can be identified in any of awide variety of manners (e.g., the merchant may pre-register with thewallet server with the accounts, the request received in act 350 mayinclude them, etc.). The wallet server then selects a set of accountscorresponding to the user that are useable at the merchant server (act354). This set includes those accounts of a type that the merchantidentified as being useable, as well as those that are of a type thatcan be converted to a format that is compatible with any one or more ofthose identified as being useable by the merchant.

The set of accounts corresponding to the user that are useable at themerchant server may optionally be further limited in act 352 based onthe restrictions on the payment accounts corresponding to the user. Tolimit the set of accounts based on such restrictions, the wallet servercommunicates with an account monitor (either implemented at the walletserver or elsewhere) to determine whether the desired purchase wouldviolate any of the restrictions associated with the payment accountscorresponding to the user. If the purchase would violate therestrictions of a particular one or more payment accounts, then thosepayment accounts are not included in the selected set of accounts thatare useable at the merchant server.

The set of selected accounts is then presented (e.g., displayed) to theuser (act 356). The wallet server then receives a user selection of oneof the accounts in the set (act 358) and forwards the account purchasinginformation for that account to the merchant server (act 360). Thisforwarding may be direct, or alternatively via a Web browser.

FIG. 7 is a flowchart illustrating an exemplary process for imposingrestrictions on payment accounts in accordance with certain embodimentsof the invention. The process of FIG. 7 is implemented by an accountmonitor 284 of FIG. 4, and may be implemented in software.

Initially, a fund transfer selection is received (act 380). The fundtransfer selection can be in response to a request to purchase goodsand/or services from a merchant, combine funds from multiple paymentaccounts, receive funds into payment account, etc. Upon receipt of theselection, the account monitor identifies any restrictions on thepayment account (act 382) and determines whether the transfer wouldviolate any of those restrictions (act 384). If the transfer wouldviolate any of those restrictions then the transfer is denied (act 386);otherwise, the transfer is permitted (act 388).

FIG. 8 is a block diagram illustrating an exemplary process fordistribution and use of a merchant-specific payment account inaccordance with certain embodiments of the invention. A user 400purchases a payment account from a merchant 402. This purchase can be anin-person purchase (e.g., physically in the merchant's store) oralternatively an on-line purchase (or purchase through some otherintermediary). Upon purchasing the payment account, merchant 402delivers to user 400 a physical card 404 that corresponds to the paymentaccount. Physical card 404 can be created in any of a wide variety ofmanners, such as including information identifying the payment accounton a magnetic stripe on card 404, in a memory device of card 404 (e.g.,in the situation of a smart card), etc. The information included onphysical card 404 is the same information that would be stored in theuser's electronic wallet for a payment account (e.g., account number,expiration date, fraud protection numbers, amount of funds in theaccount, etc.) as well as restriction information that restricts usageof the payment account to merchant 402.

Additionally, merchant 402 delivers to account processing network 406(e.g., platform 280 of FIG. 4), account information 408. Accountinformation 408 includes information necessary for network 406 to verifythe authenticity of the account for a subsequent purchase. Accountinformation 408 also optionally includes restriction information thatrestricts usage of the payment account to merchant 402. Alternatively,merchant 402 may communicate account information 408 to network 406 viaan intermediary, such as wallet server 410.

Merchant 402 may also deliver to wallet server 410 (e.g., wallet server106 of FIG. 4) account information 412 for the new payment account.Account information 412 includes identifying information for the account(e.g., account number, expiration date, fraud protection numbers, amountof funds in the account, etc.) as well as restriction information thatrestricts usage of the payment account to merchant 402. The accountinformation 412 is stored in the electronic wallet corresponding to user400 at wallet server 410. Alternatively, the account information 412 maybe stored in the electronic wallet of another user that is identified byuser 400 (e.g., the intended recipient of the payment account, such asfor a gift certificate payment account).

When user 400 (or another individual using the payment account, such assomeone who received the payment account as a gift from user 400)attempts to make a purchase in-person at merchant 402 using the physicalcard 404, the account information (stored on card 404) is transmitted toaccount processing network 406. Account processing network 406 verifiesthe integrity of the account as well as the restrictions (which might behandled by the issuing institution behind the bank ATM network, forexample) and available funds, and indicates the purchase can bepermitted if the integrity and restrictions of the account are satisfiedand sufficient funds are available. Alternatively, user 400 may attemptto make an on-line purchase at merchant 402 using the accountinformation stored in his or her electronic wallet. The purchasingprocess in this situation is the same, except that the accountinformation is transmitted to account processing network 406 from theuser's electronic wallet on wallet server 410 rather than from physicalcard 404.

The payment account distribution and use system illustrated in FIG. 8provides a mechanism via which merchants can easily distribute paymentaccounts. These payment accounts can be issued in physical card formatand/or electronic format for storage in an electronic wallet. The systemof FIG. 8 allows merchants to take advantage of an account processingnetwork 406, implemented by someone other than the merchant, to managepayment accounts such as gift certificates and rebates, thereby easingthe management functions required of the merchants to support suchpayment accounts.

There are many uses for this payment account distribution and use systemillustrated in FIG. 8. By way of example, a traditional “brick andmortar” merchant is able to issue gift certificates in the form ofplastic cards and/or an electronic format that make use of an existingaccount processing network (e.g., in a Visa® card format being verifiedvia FDC) but that are redeemable only at that merchant. Purchasing ofthese gift certificates can be via one or more merchant-branded webpages, so that the account is displayed to the purchaser as beingassociated with the merchant (and any use of the Visa®(g card formatbeing hidden from the user). This is particularly valuable for smallermerchants, as it relieves them of the burden of establishing the accountprocessing network themselves while at the same time ensuring that thegift certificates it issues are redeemable only at that merchant. By wayof another example, an online merchant can sell gift certificates in ananalogous manner, issuing them in an electronic format and/or plasticcard format. Such gift certificates are thus also restricted to beingredeemed only at that merchant, yet the merchant is not required toestablish the account processing network to verify the giftcertificates.

Although the description above uses language that is specific tostructural features and/or methodological acts, it is to be understoodthat the invention defined in the appended claims is not limited to thespecific features or acts described.
